Definitions

  • the present invention relates to a method for controlling and / or regulating a hybrid drive arrangement for a vehicle of the kind defined in detail in the preamble of claim 1.
  • the drive train of the vehicle comprises an internal combustion engine which can be coupled via a clutch to an input shaft of a transmission with variable transmission. Furthermore, the input shaft is assigned at least one electrical machine, which can be switched between a regenerative or motor operation.
  • the electric machine can be used in motor operation for driving the vehicle and in regenerative operation for charging an energy storage.
  • the energy store can supply the necessary energy for operating the electric machine.
  • the electric machine located in the generator mode is driven by the internal combustion engine.
  • the energy storage devices After very long periods of downtime or after a long period of service in the vehicle, the energy storage devices are completely discharged and no longer ready for operation. In order to make the energy storage ready again, it is thus necessary to recharge it. Usually, the energy storage is recharged in the workshop with a charger. This disadvantageously requires an external source of energy.
  • a method for controlling an operation of a motor vehicle with a hybrid drive arrangement which comprises an internal combustion engine and an optionally motor or generator operable electric machine, wherein the electric machine in the regenerative mode loads an energy storage.
  • the combustion engine operates the electric motor at a constant torque.
  • the engine speed is here in a fixed, defined by the efficiency map of the electric motor range.
  • WO 02/086343 A and the WO 03/066367 A are a speed control of the engine specified by means of a clutch. According to the WO 03/066367 A is controlled when the engine speed falls below a specified threshold, while at the WO 02/086343 A the regulation by means of the clutch takes place when a certain threshold value is exceeded.
  • the invention is based on the object to propose a method of the type described above, with which a clutch control is enabled, which is not limited in time.
  • a method for controlling and / or regulating a hybrid drive arrangement for a vehicle having at least one internal combustion engine and at least one electric machine, which are at least temporarily coupled via at least one clutch to the input shaft of an automated transmission for driving the vehicle, wherein at least one energy storage which is operated by the internal combustion engine as a generator operated electric machine and wherein in a permanent-magnet synchronous machine as the electric machine, a target speed below a corner speed is specified during the charging process.
  • a completely discharged energy storage can be charged without additional external energy by the target speed within a basic speed range, ie below the buckling speed or the corner speed of the synchronous machine is held.
  • the internal combustion engine of the vehicle can be started by means of a conventional starter.
  • the clutch is closed and the internal combustion engine can drive the electrical machine in generator mode to start charging the energy storage. Due to the fact that the setpoint speed lies below the corner speed, no energy is required for the field weakening normally provided. As a result, it is possible to charge the empty energy store without assistance from the vehicle, so that a self-sufficient system is realized.
  • the clutch control is used to control the setpoint speed during the charging process.
  • the desired speed range can be maintained during loading.
  • the charging of the energy storage is thus speed controlled with the synchronous machine, which is technically simple and stable realized.
  • the clutch is operated with the clutch control in the slip range to keep the target speed of the synchronous machine in the basic speed range. This is necessary, since usually the idling speed of the internal combustion engine is above the corner speed usually at 300 to 400 revolutions / minute. In this way, the clutch controlled a corresponding moment is given, so that the speed of the synchronous machine is kept when charging the energy storage below the corner speed.
  • the invention will be explained in more detail with reference to the drawing.
  • the sole figure of the invention shows a diagram with a torque curve over the speed of a permanent magnet synchronous machine.
  • the permanently excited synchronous machine initially has a constant course of the torque m up to a corner speed or buckling speed n_eck.
  • the section in which the constant course of the torque m exists is referred to as the basic speed range I. After that, the torque m decreases continuously. This area is referred to as field weakening area II of the permanent magnet synchronous machine.
